4.2.4 Parameter Modification Mode
The Parameter Modification mode is accessed by pressing the CHANGE key when an
adjustable parameter is displayed. In the Main Menu, a password is then requested; in the
Extended Menu, a password is requested only for parameters requiring password No. 2
(because password No. 1 has already been entered to access the Extended Menu). For
details on passwords, see Section 4.4 on page 4-9.
The Parameter Modification mode is indicated with a colon displayed on the bottom line,
at the left of the numerical value or choice to being modified. The value of the parameter
can then be changed using the
UP and DOWN keys; the modification is validated with
ENTER .
4.2.5 Power-up Mode
Depending on start-up conditions, the H201T i executes one of the following sequences:
• Normal power-up (power-off longer than five minutes): See Section 4.2.5.1 on page 4-6.
• Short power-up (power-off shorter than five minutes): See Section 4.2.5.2 on page 4-7.
• First power-up (after reconnection of battery): See Section 4.2.5.3 on page 4-7.
4.2.5.1 Normal Power-up (Power-off Longer Than Five Minutes)
This sequence begins with a self-test sequence that lasts approximately 40 seconds; then
the Main Display mode is shown on the display. Table 4-2 on page 4-6 details the self-test
sequence.
